Lawl and lawm are two Arabic complex particles consisting of the conditional particle (law) 'if' followed by (l) for the first and (m)for the second; both meaning 'not'. This gives the new meanings of (if not; except for; were it not for; had it not been for) to both complex particles (Hasan, 1974: 512). However, these two particles have meanings and functions other than what is indicated by their forms they include. The following discussion tackles these particles in detail.
